CSyncCollection v1.08 A templatized collection with thread synchronization

Welcome to CSyncCollection, an MFC class which implements a templatized collection which implements thread synchronisation with timeouts for both adding and removing. In other words when you "Add", you can specify a timeout to wait for if the collection is full and if when you "Remove" data from the collection you can specify a timeout to wait for if the collection is empty. Making the class templatized means that you can store any type of data you want on in it. In addition templates are used to define various collection types. The code comes with predefined templates for both a stack and queue collection.

The enclosed zip file contains source for the class and a test program which implements a simulation of the classic consumer / producer thread synchronisation example.

Updates

v1.0 (26 January 2002)

• Initial Public release

V1.01 (6 April 2002)

• Sorted out some linker problems for the Win32 Debug and Win32 Release build configurations.

V1.02 (7 April 2002)

• Added a CEvent to the main class to allow synchronisation with data becoming available in the collection without actually having to remove it.

V1.03 (23 November 2003)

• Fixed a potential thread race condition in CSyncCollection::Remove

V1.04 (26 November 2004)

• Fixed a number of compiler warnings when the code is compiled on VC .Net 2003

V1.05 (30 May 2005)

• Now uses a auto-reset event to signal that items are available instead of a manual reset. Also the event is now created using the Win32 API rather than using the MFC CEvent wrapper class.
• Updated the text in some of the TRACE statements.

V1.06 (10 April 2006)

• The CSyncCollection class now provides Lock and unlock methods to allow external synchronisation.
• CSyncCollection::GetSize, Add, Remove & Close now includes a parameter which decides if internal locking should be done. Again this allows more fine tuned external synchronisation of the class
• Addition of a CCSYNCCOLLECTION_EXT_CLASS macro to make it more easier to use the class in an extension dll.
• Updated the documentation to use the same style as the web site.
• Did a spell check of the documentation.

V1.06 (10 April 2006)

• The CSyncCollection class now provides Lock and unlock methods to allow external synchronisation.

V1.07 (2 May 2006)

• Removed the need to have the collection class methods virtual. After all you can think of C++ templates as compile time polymorphism while virtual functions give you runtime polymorphism.

V1.08 (7 July 2008)

• Updated copyright details.
• Removed the CSYNCCOLLECTION_EXT_CLASS proprocessor value as it is not required since the class is template based.
• The code has now been updated to support VC 2005 or later only.
• Updated the sample app to clean compile on VC 2008
• Code now compiles cleanly using Code Analysis (/analyze)
• Code now uses newer C++ style casts instead of C style casts.
